How to calculate area and perimeter of a triangle in C++

Answer 1

#include <iostream>
#include <iomanip>
using namespace std;

int main()
{
	int _base = 12, high = 13, a = 6, c = 8;

	cout << "area = " << fixed << setprecision(2) << (float)(_base * high) / 2 << endl;
	cout << "perimeter = " << _base + a + c << endl;

	return 0;
}

/*
run: 

area = 78.00
perimeter = 26

*/
